Mary buys concert tickets for $45 each plus a service fee of $15 for the order.
This situation is:
Proportional, because you can figure out the total cost.
Linear, because all of the tickets are the same price, but non proportional because you add the service fee
Not a function, because you have to pay a service fee.
A function but non linear because each ticket costs more than the fee.
Which of the following sets of ordered pairs represents a proportional relationship?
{(0, 5)(1, 10)(2, 15) (3, 20)}
{(3, 15)(5, 25)(8, 40) (12, 60)}
{(4, 6)(8, 6)(2, 6)(5, 6)}
{(3, 6)(4, 8)(5, 10) (3, 12)}
